Group 0 name Corresponds to the control (unexposed) group for case-control studies
MSM
Group 1 name Corresponds to the case (exposed) group for case-control studies
Westernized
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Westernization describes a population with incremental urbanization, profound lifestyle changes, including but not limited to, transition from autarchic means of producing food to controlled food production chain, increased hygiene and accessibility to modern medicals, introduction of food sterilization, increased exposure to pollutants, and switch from high-fiber simple diets to high-fat high-protein processes that has been undergoing for centuries.
Group 0 sample size Number of subjects in the control (unexposed) group
93
Group 1 sample size Number of subjects in the case (exposed) group
481
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
6 Months
